FREDERICK J. HENRIOHSEN, OF RACINE, WISCONSIN, ASSIGNOR TO THE HENRICHSEN MANUFACTURING COMPANY, OF SAME PLACE.

BROADCAST SEEDER.

SPECIFICATION forming part of Letters Patent No. 423,997, dated March 25, 1890.

Application filed December 22, 1888. Serial No. 294,355. (No model.)

To all whom it may concern:

Bezfit known that I, FREDERICK J. HEN- RICHsEN,of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Broadcast Seeders, of which the following is a specificatiQn.

My invention relates to broadcast seeders; and it consists in a novel construction and arrangement of parts hereinafter set forth.

In the drawings, Figure 1 is a perspective view of my improved distributer; Fig. 2, a perspective view of the parts separated; Fig. 3, a vertical sectional view; Fig. 4, a perspective view of the bottom of the distributer, and Fig. 5 a perspective view of the adjustable distributing gate or slide.

A indicates the upper hopper secured to or formed upon the lower hopper B, and Oindicates the distributing-plate secured to the upright shaft D, as shown in Fig. 3. Fitting into the upright wall of the hopper B is a slide or plate E, which is designedto cover openings in the hopper-wall and to regulate and control the discharge of seed from the hopper. The slide. is provided with notches or openings at in its lower edge, to which are applied slotted plates 1), adjustably secured to the inner face of the slide by means of a screw 0. By adjusting the plates upon the slide and the slide as a whole relatively to the hopper a nicety of adjustment is secured. Mounted upon the shaft D within the hopper is a wheel or agitator F, the arms and body of which are made of rubber or other elastic material, which during rotation will not bruise the seed or grain within the hopper. This rubber Wheel is provided with a metal bushing G, having a rib d cast integral therewith, which rib is adapted to fit into a groove 6 in shaft D, as shown in Fig. 3, said wheel being held in position upon the shaft by means of a thumb-nut f, screwing upon the end of shaft D, as shown. This distributing-plate O, to which I have referred, is provided on its upper face with radial wings or blades H, provided at their inner ends with hinged or pivoted gates I, which terminate close to the outer walls of the hopper B. The gates are provided with perforated lugs g,

through which passes a bolt or stem h, secured to the plate 0, as shown. The bolt is encircled by a coiled spring 2, the ends of which bear upon the wing H and gate I in such manner that the latter is held normally in line with the wing close up to the hopper, but is permitted to yield in case stones, nails, or other foreign matters find their way into the machine, thereby preventing breakage of the parts.

Cast upon or otherwise secured to the under side of the plate 0 are lugs j, with which lugs k, secured to or formed upon a clutchcase J, are adapted to engage. This case J is formed with a bevel tgear-wheel K, to which motion may be imparted in any suitable manner, said case and its wheel being mounted loosely upon the shaft D, so as to permit a limited movement thereon. The degree of movement will of course be limited by the lugs j 70, which latter, when in engagement, lock the distributer-plate O to the case J, and thereby cause the rotation of the plate.

In order to take up the jar due to the initial movement or starting'up of the machine, I place within the case or shell J a coiled spring L, one end of which is secured to the shell J and the other end to the plate C. 011 motion being imparted to the wheel K the case J is moved or turned slightly and the strain due to sudden starting of the machine taken up by the spring L, which latter will be coiled up until the lugs k strike the lugs j, and when the plate 0 and case J and wheel K are thus locked together further rotation of the wheel K will cause a corresponding movement of the distributing-plate C.

By reason of the bottom of the hopperB being closed, no seed, particularly fine grassseed, is permitted to enter between said hopper and plate 0 and be thereby ground.

It is clear that the case or shell J may be omitted, in which case the wheel K would be provided with two arms, which would serve as lugs to engage the lugs j on the plate 0.

In use the hoppers AB are secured rigidly in position, and the shaft or aXle D is supported at its lower end by a socket or hearing. (Not shown.)

The device herein shown is designed to be applied to the rear end of a wagon and receive motion from the driving-wheel thereof through intermediate connections, (not shown and forming no part of the present invention.)

The thread out upon the upper end of the shaft or axle D is preferably a left-hand thread, so that any tendency there might be of the thumb-screw to loosen during the rotation of the feeding-Wheel is obviated.

Instead of employing precisely the construction of springhingejoint shown between the wings or blades and the gates, any equivalent form of joint may be used.

N 0 claim is made herein to matters embraced in my application, Serial No. 315,37 7, filed as a division of this application.

Having thus described in yin ven tion, whatI claim is 1. The combination, in a seed-sower, of a FREDERICK J. HENRICI-ISEN.
